Not every underwear brand mentions humanitarian efforts in their product slogan. Then again not every company is WearPACT — the smart, values-driven eco-brand launched in San Francisco last year.

WearPACT didn’t start with cute underwear and then look to align itself with an encouraging mission statement. Instead, founders Jason Kibbey and Jeff Denby began with a mission to have a positive impact on the world through a sustainable, responsible business model. The product is the medium for their eco-conscious message.

Fortunately for us, that product is a great one. WearPACT designers have created stunning textile prints with earth-friendly inks and dyes. Don’t look for bright white undies here; the harsh bleaches needed to achieve the color aren’t worth it environmentally. WearPACT underwear is 95% organic cotton with the 5% elastane content, helping maintain the shape of the product and therefore extend its life.

The limited-edition Winter Lights collection, designed by Yves Behar, appeals to the nostalgia and festiveness of holiday lights in its prints. More importantly, it’s going to do a lot of good this season.

Working in collaboration with the organizations EarthSparks International and Citizen Effect, WearPACT is donating one solar-powered lantern to a Haitian family without electricity with every sale of a Winter Lights item. Lighting up tented communities in Haiti helps to tackle “energy poverty” and promote safety, health and education in the devastated country.

WearPACT hopes to distribute 1,000 lanterns, and you can participate in their mission by stuffing a stocking or two with their undies. There are boy shorts, bikinis and thongs for her, boxer briefs and trunks for him.

If you don’t care for patterned underwear, check out WearPACT’s Essentials collection. The brand carries three other collections too, all boasting innovative prints and aligned with global-outreach initiatives. Most pieces cost about $20 and are available through their website, so no excuses. You can’t go wrong here.

Oh, and WearPACT also has the best motto in the business: “Change starts with your underwear.” They’ve GOT to put that on a T-shirt!
